Like any good grammar junkie, I keep a list of resources for when questions arise about the English language. The following are some free sites that I find myself referring to time and time again. They have been so helpful over the years that it would feel stingy not to share them.
Purdue University has a wonderful set of online materials aimed at helping people improve their writing. Though some parts of the lab are dedicated specifically to Purdue students, many of them are more broadly applicable. The sections on grammar and the writing process are particularly good.
Amherst College has also curated a lovely set of writing resources. Its collection features an aggregation of essays from wonderful places. One of my favorite pages discusses obstacles to writing, which has great features on anxiety and procrastination.
For questions about word use, Grammarist is a great resource. The website is constantly growing and adding information about the English language and grammar.
Paul Brians has created a fabulous site about the most common mistakes writers make. The site can be a bit difficult to navigate, but it is a great way to answer tough language questions.
Grammar Girl offers short tips and easy guidelines about grammar, punctuation, and writing style. Because this site is technically a part of QuickandDirtyTips.com, it can be a little difficult to find some of the information available. Regardless, she provides excellent information. For some of her more popular discussions, see her writing on affect versus effect and quotation marks.
How could I write about online grammar guides without talking about the Oxford Dictionaries? Though the site can be overwhelming to beginners, it provides a thorough exploration of all aspects of the English language.
